SPRIlZNKLER.

Specification of Letters Patent. Patented June 7, 1910.

Application filed August 7, 1909. Serial No- 511,726.-

vention is to design a novel and sim lestructure of sprinkler especiallyadapted or use in connection with gas washing tanks.

Other objects, andthe advantages of .my invention, will appear in thecourse of the following description in which reference is made to theaccompanying drawings, forming a part of this specification, and inwhich, Figure 1 is a vertical sectional view through a portion ofa gaswashing scouring tank, illustrating my improved sprinkler in elevationtherein. Fig. 2 1s a plan view of my improved sprinkler removed. Fig. 3is an enlarged vertical sectional view through the nozzle and nozzlehead, with the sprinkling .arms removed. Fig. 4. is a transversesectional view on the line H of Fig. 3. Fig. 5 is a transverse sectionalview through one of the s rinkler arms, and illustrating the spray reector and its manner of connection, and Fig. 6 is a longitudinal sectionthrough the parts shown in Fig. 5.

In the practical'embodiment of my invention as herein shown, I providean inlet pipe 1 arranged vertically, and externally threaded adjacentits upper end, upon which upper end is disposed the lower externallythreaded end of the nozzle pipe 2, which is'closed at its upper end by athreaded ca 3, and provided adjacent said upper en with a series of'openings l, which lead Within the bore of a nozzle head 5, having aseries of radially threaded o enings 6, through; its wall, and isrovidbd with a contracted lower portion fitting snugly about pipe 2below its perforations 4. Within the bore of head 5, between itsopenings 6 and the lower end thereof, is arranged packing material8,'and a packing ring 9 oldin said material, which prevents the escapeof 'quid between the pipe 2 and the contacted portions 7 of sad head,the lower end of said head being flared and grooved at 10 whereby tocollect the fallin spray uponthe exterior surface of the hea and permitthe same to drip from its lower end away from the nozzle pipe 2. Aplurality of radial-outstanding' sprinkling arms 11 have their innerends threaded to be screwed within the openings 6 of the head 5, saidarms. being provided intheir length with a/plurality of dischargeopenings, arranged in longitudinally extending spiral series, andthreaded for a purpose to be hereinafter described. As shown, the arms11 are inclined outwardly and downwardly from the head 5, and are closedat their outer ends by end caps 12, beyond their outermost waterdischarge openings, thus forming pockets at their ends for sediment andother impurities in the water which in the ordinary con-v struction ofsprinklers tend to clog up said discharge openings.

As shown in Figs. 5 and 6, the water discharge openings of. the arms 11being, as before stated threaded, are adapted for the reception ofthreaded nipples-13 each of which has anoutstanding bracket arm 14 and adeflector'plate 15, the inner edge of which is inclosed within thematerial of the nipple 13 at one side of its opening 16, said deflectorplate 15 being of suitable flexible material whereby it may be angularlyadjusted within the jet of liquid flowing outwardly through nippleopening 16 by means of a set screw 17 tapped through the outer end ofbracket arm 14. In this manner, the water discharge openings of the armsor essarily of minute proportions (thus endangering clogging) wherebyto'permit a fine inner end rotatably engaged within a depression withinthe end cap 3 of. said nozzle pipe 2, the said rod 19"and said head 5being ordinarily locked together for rotation by means of-a nut 20. Therod may be provided upon its outer end with a hand'wheel 21, and-whenthe sprinkler is used in connection with a gas washing or scouring tank,said rod extends upwardly through the .upper end or hood 22 of' thescouring tank 23 more particularly the nipples 13 are not necandthesaidhand wheel 21 thus forms a means for indicating whether or not thesprinkler is in operation As shown particularly in Bi 3, collars 24: and25 are screwed upon the ad acentthreaded ends of the inlet pipe 1 andnozzle pipe 2 respectively, said collars abutting one another and beingprovided with transverse registered openings through which suitablefastening means may be secured in the present instance the inner angularends 26 of i in the same plane, and the openings of the othel 'alternatearms in planes between the planes of the openings of the first mentionedarms.- 1

Having thus described my invention, I claim 1. A rotary sprinklerembodying a plurality of outwardly and downwardly inclined sprinklerarms, each having a plurality of dischargeopenings and a removable endcap upon its outer end forming a sedimentpocket beyond the outermostopening.

2. In a rotary sprinkler, a sprinkler arm having a discharge opening,an] apertured nipple, secured within said opening, a flexible baflieplate having one edge anchored within the material of said nippleadjacent its apertures, and an adjusting screw tapped 'through'a portionof said nipple plate to ad-t just. the same.

' 3. In a device-of the character described,

. ceases vthe combination with a casing, of a nozzle pipe centeredwithin theupper portion of said casing, a nozzle head surrounding theendof said nozzle pipe,'sprinkler arms extending from said head, a rodthreaded through said head to rotate therewithand bearin uponthe -nozzlepipe end, sai rod extend ng upwardly through said casing, and providedwith a hand wheel exteriorly thereof, substantially as described.

4. In av device of the character described, the combination with acasing of a water pipe, a nozzle pipe. disposed thereon, said pipesbeing provided with abutting collars having registering transverseopenings, a nozzle head disposed upon said nozzle plpe, sprinkler armsextending'fromsaid head,

and rods extending radially from said pipe and having angular inner endslocked through the transverse openings of said collars, and having theirouter endssecured to the casing, whereby to center the said pipes withinthe said casing, substantially as described. w

5. A sprinkler of thp character described, comprising a rotary nozzlehead, a sprinkler arm arranged upon said nozzle head and provided withan aperture, a flexible baflie plate arranged upon said sprinkler arm'adjacent said aperture whereby the water passing through said aperturemay strike against said bafile plate and be sprayed, a sorew arrangedupon said sprinkler arm in engagement with said" flexible baflle plateand adapted to angularly adjust said baffle plate,

substantially as described. 1 In testimony whereof I atfix my signaturein presence of two witnesses. 1
